GW9-12/40.5 Outdoor High Voltage Disconnector
=This series of outdoor high-voltage disconnector is a single-phase AC 50Hz high-voltage switchgear, which is used in the power system with a rated current of 10KV, and is switched on as a voltage and no load or for the purpose of isolating the power supply. This disconnector is operated with an insulated rod.
Three-series structure is single, economical and easy to use.
This product is a single-break vertical open structure, and the single-pole disconnector insulator is installed on their respective underframes, which is mainly composed of a base, a pillar insulator, a leading electrical circuit part, and a self-locking device.
The gate knife structure is used to open and close the gate to achieve cutting and closing the line. Each phase blade is composed of two conductive blades, and both sides of the blade are equipped with pressure storage springs, and the height of the spring can be adjusted to obtain the contact pressure required by the switch blade.
When the switch is opened and closed, the insulating hook rod is used to operate the mechanism part, and the gate knife has a self-locking device.
